They function as clear, standard prescription glasses indoors or at night, but expose them to the sun, and the automatically convert into sunglasses. Take away the sun and they revert back. You never again need to buy or carry around two sets of prescription glasses. They come in gray or brown. They provide 100% protection from UVA and UVB light. They are available in both prescription and non-prescription form, and in a variety of specialty applications, such as bifocals and progressive lenses. They are available in virtually every lightweight lens material and design.
What can be better than that?
Anti-Glare Coatings for Transition Lenses!
Yes, transition lenses accept anti-glare (AR) coating, and there are good reasons to have one applied.
An anti-glare coating makes your glasses look better to others. They restrict stray reflections on the front of your lenses, the reflections that mask your eyes. You spend time picking out the most stylish frame, the one that best compliments your face; why hide your eyes behind a mass of reflected light? An AR coating renders your lenses nearly invisible to onlookers.
An anti-glare coating also makes your glasses look better to you. They reduce the amount of light that bounces off the inside of your lenses and allow more light to pass through, thereby increasing your visual acuity as well as improving contrast. Ever strain your eyes while driving at night, or from extended periods spent in front of your TV or computer monitor? That strain comes from fighting off the glare your eyes encounter. Reduce the glare and you reduce the amount of work your eyes have to do.
Anti-glare coatings are particularly useful if you wear high index lenses. The higher the refraction index of a material, the more light they reflect, and high index lenses can let in up to 50% more light than regular plastic lenses (approximately 8% of incoming light is reflected by standard plastic, while high index plastic lets in 12%).
Modern AR coatings have improved to the point where they can allow 99.5% of incoming light to pass through to your eyes. This means increased visual acuity for you and a full view of your eyes for others. See and be seen, better than ever.
An AR coating is a minor investment with a lot of payback. If you’ve chosen transitional (or photochromic) lenses, you’ve already reduced your eyewear needs to one pair and you’ll be using it everywhere, day in and day out. Make it the best it can be with an anti-reflective coating.
